5. Pharmacological Properties

Pharmacotherapeutic group: Antibiotic

ATCvet Code: QJ01AA06

5.1 Pharmacodynamic properties

Oxytetracycline is a bacteriostatic antibiotic that inhibits protein synthesis in susceptible bacteria. Inside the cell it binds irreversibly to receptors on the 30S subunit of the bacterial ribosome where it interferes with the binding of the aminoacyl-transfer RNA to the acceptor site on the messenger RNA ribosome complex. This effectively prevents the addition of amino acids to the elongating peptide chain, inhibiting protein synthesis. The product is specifically formulated to provide a prolonged action resulting in sustained antibacterial activity.

Oxytetracycline had been shown to be effective in vitro against the following bacterial species: Bordetella bronchiseptica, Corynebacterium pyogenes, Erysipelothrix rhusiopathiae, Escherichia coli, Haemophilus somnus, Pasteurella haemolytica, Pasteurella multocida, Salmonella dublin, Staphylococcus aureus, Streptococcus agalactiae, Streptococcus faecalis, Streptococcus pyogenes and Streptococcus uberis.

5.2 Pharmacokinetic properties

Blood levels persist for at least 4 days after administration by the intramuscular route. Maximum blood levels are achieved between 4 and 8 hours following intramuscular administration.
